Biology A2

1. Glucose->2xTP
2. Using 2xATP

1. TP->Pyruvate
2. ADP + Pi -> ATP
3. NAD->redNAD

1. Low temp.
2. Dry to constant
3. Carbon is ~50% of dry mass

1. Total amount of chemical energy convert by plants from light energy

1. ~50% of GPP lost as plants respire
2. NPP=GPP-R

1. Nitrogen compounds converted to ammonia
   1. By saprobionts
   2. In dead organisms
   3. In urine and faeces

1. Ammonium ions converted to nitrates

1. Feed on dead plants and animals
2. Extracellular digestion

1. Blocks light
   1. Plants can't photosynthesise
      1. No oxygen produced
      2. Plants die
         1. More bacteria

Anexos:

• Biology~AS

1. Transcription enzymes no longer complementary
   1. Decrease transcription
      1. Hypermethylation=more growth
      2. Hypomethylation=less growth

1. Chromosomes less condensed

1. Cancerous
2. Fast growing
3. Can break and spread around body

1. Not cancerous
   1. But can become cancerous
2. Fiborous
3. Cause blocakges
4. Slow growing
5. Pressure on organs
